Earth Hour for kids, with kids and by kids.
My daughter is 6 years old and in the last 3 years, she's been with us, as we participated in some of the organized Earth Hour activities. She's very much "Earth Hour-aware". When we get home at night and she sees that most of the lights are off, with just the TV lights hinting that somebody's home, she'd remark, "O si Lola naka-Earth Hour." She has associated energy conservation acts with Earth Hour. And yes, she's knows the significance of Earth Hour and the ideals behind it. It's no surprise as her dad and mom espouse living the green life.
